  • Myth vs Fact

    Myth vs Fact


    Freightliner Truck On HighwayThe Filter Minder® filter monitoring device makes it easy for you to tell when it's time to change filters.  

    The myth is that an automotive air filter should be changed about every 6,000 miles, or when it "looks dirty."

    The fact is that a certain amount of dirt in an air filter actually increases its filtering efficiency by reducing the size of the holes in the filter media which helps stop smaller dirt particles.

    This means that instead of a maximum life of 6,000 miles, the typical air filter may actually last anywhere from 60,000 to 100,000 miles!

  • When To Service?

    When To Service?

    A Dirty Filter Element Is Better Than A Clean OneAir filter restriction is not time or miles dependent.

    Mileage of as much as 300,000 to as little as 5,000 miles have been reported when restriction is reached.

    It is important to know the highest full load restriction that occurred during the vehicle operation in order to service BEFORE the redline.  

    After an element has reached its redline value, it only takes a little more contaminant before high fuel consumption and poor engine operation occurs.  Don't Dust Your Engine!

  • INTRODUCING

    The Filter Minder® Air Line Filter and Indicator

    We are pleased to introduce a new addition to its portfolio of filter monitoring products.... the innovative, versatile and convenient Air Line Filter and Indicator. Click through the showcase to learn more and view the ALFI Animation.

  • Air Line Filter and Indicator
    Early Filter Life 

    In routine use, air flows through the Air Line Filter, trapping particles.

    The Air Line Filter and Indicator (ALFI) protects against harmful debris and contaminants in high pressure air lines in a wide variety of industrial, transportation and on-site applications requiring compressed air or gas.  

  • Air Line Filter and Indicator
    End of Life

    Extreme clogging will extend the red indicator (as device progresses towards full bypass mode) until it is fully extended, locked, and requires replacement. Build-up of debris will open the bypass to keep air flowing.

    When restriction becomes excessive, a bright red indicator deploys from the device, indicating it is time to change the filter.

    The filter cartridge is replaceable with a 1-1/4” wrench/socket and is ready again to protect your operating assets in just seconds.

Filter Minder® Single Position Switch Indicator

Air Filter Restriction Monitoring Indicator / Switch

Single Position & Signal Indication / Threaded Mount

 

How It Works

The Filter Minder® Single Position Switch Indicator is a combination single position indicator and switch. The window turns red when the maximum recommended air filter restriction has been reached and a signal is sent to the filter warning light on the dash or to the engine computer to record as a diagnostics fault. The warning light locks on until the indicator is reset.

The Filter Minder® should be reset whenever the service indicator is checked to determine air filter restriction or when a new air filter is installed. Push the reset button at the end of the service indicator, and the position indicator will return to zero.

Filter Minder® Non-Locking Air Switch

Air Filter Restriction Monitoring Switch

Triggers Air Filter Warning Light / Non-Locking

 

How It Works

The Filter Minder® Non-Locking Air Switch continuously monitors the engine air filter and tells when filter is restricted. Triggers air filter warning light via the engine computer or directly to the warning light. Used for air filter monitoring on diesel, gas, and alternate fuel engines, as well as other applications where low vacuum/pressure monitoring is required.

Filter Minder® Graduated Switch

Air Filter Restriction Monitoring Gauge / Switch

Graduated / Electrical Indication / Threaded Mount

How It Works

A combination graduated indicator and switch, the Filter Minder® Graduated Switch features a position indicator that progressively fills the window as air filter restriction increases, locking at the highest restriction. When it reaches the red zone, or highest recommended restriction, it sends a signal to the filter warning light on the dash or to the engine computer to record as a diagnostics fault. The warning light locks on until the indicator is reset.

The Filter Minder® should be reset whenever the service indicator is checked to determine air filter restriction or when a new air filter is installed. Push the reset button at the end of the service indicator, and the position indicator will return to zero.
